Skip packing GraphModule.recompile() codegen bookkeeping as module state

torch.fx.GraphModule.recompile() writes `_code`/`_lineno_map` (and
`_in_spec`/`_out_spec` for pytree codegen) straight into the module's
__dict__. Thunder's attribute-modification tracking mistook these
codegen-cache internals for real module state and tried to pack them
into the epilogue trace, asserting when the value was a plain str/dict
instead of a Proxy. Fixes test_higher_order_inplace_alias_update
failing intermittently in CI depending on test order/dynamo cache
state.
